Geoff is an Interdisciplinary Ethics Fellow at Stanford University. He is based between the Center for Ethics in Society (EiS) and the Institute for Human-Centered Artificial Intelligence (HAI). He completed an AHRC funded PhD in the Department of Philosophy at the University of Bristol in May 2020. His PhD developed an account of how automated vehicles morally ought to moderate their speed in cases where they are severely uncertain about the classification of proximate objects and how those objects will behave. Most of Geoff’s work is about the ethics of artificial intelligence, but his work draws on ideas from moral and political philosophy, formal epistemology, decision theory, criminal law, philosophy of science, and philosophy of biology. He is also interested in what philosophy can learn from theoretical computer science. Most recently he was a Research Assistant at the Leverhulme Centre for the Future of Intelligence at the University of Cambridge. Geoff worked on Dr. Rune Nyrup’s project “Understanding Medical Black Boxes.” He has taught formal logic, social choice theory, political philosophy, and research methods for social sciences. Geoff was also President of the British Postgraduate Philosophy Association and an Executive Committee Member of the British Philosophical Association from 2018 to 2019.
